动态虚拟地景的设计与实现
|
摘要
无人机(UAV)有很多优点，隐身性好、机动性强、成本低廉，特别是无飞行员伤亡，在现代战争中的作用愈加重要。无人侦察机设备复杂、价格昂贵，用实际装备进行训练，费用高、风险大，并受空域、气象等因素制约，组织飞行训练难度很大。正在研制的无人机模拟训练系统要具有与实际装备相同的操作和显示特性，能模拟无人机飞行的全过程，侦察图象的模拟是该系统的重要组成部分。
本论文分析了无人机侦察图像的各种特性，给出了虚拟地景的3D建模方法，并采用了多种运动模型，很好地实现了无人机模拟训练时侦察图像的实时仿真。此外还分析了系统的软硬件结构，给出了用于系统内通信的网络模型和串口模型。
UAV(Unmanned Air Vehicle) has many advantages, such as good invisibility, strong flexibility, and low cost. More important, no pilots will die using UAVs. In modern war, UAV is more and more widely used. UAV composes of many complex devices, which is very expensive. If using real UAV in trainning, we have to face a high cost, a serious risk, and a limit of aerial condition and weather. The developping "Simulating Trainning System of UAV" has the same characteristics of operation and display as real UAV system. It can simulate the whole process of flying. An important component of it is the simulation of reconnaissance image.
In this article,the author gived out a project on 3D modelling basing on the analysing of the characteristic of UAV s reconnaissance image. With moving models, a good real-time simulating reconnaissance image has been accomplished. Furthermore, a network model and a serial-port model are employed to implement the commucation within system, which is also referred in this article.
